The convergent synthesis of the polycyclic alkaloid (-)-nakadomarin A (1) is reported. The synthesis plan identified macrocyclic lactam 4 as one of the important synthons (eight steps). The other synthon (five steps) was bicyclo[6.3.0] lactam 5 containing a single stereocenter that controlled all of the subsequent stereochemistry during the assembly process. A silyl triflate-promoted cascade of 4 and
